Embodiment 1

[0047] refer to Figure 1 to Figure 5 , the accumulator according to Embodiment 1 of the present invention will be described. figure 1 and figure 2 is a schematic cross-sectional view of the accumulator of Embodiment 1 of the present invention, figure 1 Indicates the stretched state of the metal bellows, figure 2 It shows the state of the metal bellows shrinking. image 3 It is a partially enlarged schematic cross-sectional view of an accumulator according to Embodiment 1 of the present invention, and is an enlarged cross-sectional view near a vibration-damping member. Figure 4 It is a plan view of the damping member of Example 1 of the present invention. Figure 5 It is a side view of the damping member according to Example 1 of the present invention, and is a view of the damping member viewed from the outer peripheral surface side.

Embodiment 2

[0067] Figure 6 Example 2 of the present invention is shown. In this embodiment, a configuration in which the structure of the damping member is different from that of the first embodiment is shown. The other configurations and functions are the same as those in Embodiment 1, so the same components are given the same reference numerals and their descriptions are omitted.

[0068] Figure 6 is a schematic cross-sectional view of an accumulator according to Example 2 of the present invention, showing a state in which the metal bellows is stretched. The vibration damping member 190X of this embodiment has the main body part 191 and the fitted part 192 similarly to the vibration damping member 190 of the said 1st Embodiment. However, unlike the vibration damping member 190 of the first embodiment, the vibration damping member 190X of the present embodiment does not have the guide portion 193 . In the vibration damping member 190X of the present embodiment, only the radially o...

Embodiment 3

[0070] Figure 7 Example 3 of the present invention is shown. In this embodiment, a structure in which the installation position of the damping member is different from that of the first embodiment is shown. The other configurations and functions are the same as those in Embodiment 1, so the same components are given the same reference numerals and their descriptions are omitted.

[0071] Figure 7 is a schematic cross-sectional view of an accumulator according to Example 3 of the present invention, showing a state in which the metal bellows is stretched. In the first embodiment described above, the configuration in which the damping member 190 is provided at the center position in the axial direction of the metal bellows 130 is shown. However, it is effective to install the vibration damping member 190 at the position where the vibration in the direction perpendicular to the axial direction is the largest on the metal bellows 130 . In this way, the position where the vibr...

Abstract

An accumulator is provided, the purpose of which is to stabilize the mounted state of a damping member while alleviating impact on a metal bellows. Provided is an accumulator (100) in which a damping member (190), which is configured to freely slide over the inner peripheral surface of a pressure container (110) and which suppresses vibration of a metal bellows (130) while maintaining a gap between the metal bellows (130) and the inner peripheral surface of the pressure container (110), is mounted in at least one location in a plurality of annular dips in the metal bellows (130) in which a plurality of annular bumps and a plurality of annular dips are alternately formed; the accumulator (100) characterized in that diametrally inner-side tips of the damping member (190) are fitted with the dips, and diametrally outer-side tips of the damping member (190) are longer on the diametrally outer side than the bumps of the metal bellows.

Description

technical field [0001] The present invention relates to an accumulator for releasing a large amount of energy for a short time, mitigating pressure fluctuations, and the like. Background technique [0002] Conventionally, an accumulator having a metal bellows has been used in order to release a large amount of energy in a short time, to moderate pressure fluctuations, and the like. For this type of accumulator, when the metal bellows vibrates due to external vibration, in order to prevent the metal bellows from colliding with the pressure vessel, a sliding ring that also functions as a bearing is provided at the front end of the metal bellows. However, the slide ring alone may not be sufficient under various conditions such as the length of the metal bellows. On the other hand, an intermediate ring (vibration damping member) that performs the same function as the slide ring is also provided at an intermediate position in the axial direction of the metal bellows. refer to ...
